Iron Ore Iron ore is the rock that contains iron elements or there are iron deposits in it. Economical iron deposits are generally in the form of magnetite, hematite, limonite, and siderite [3]. Iron ore deposits can be formed primary or secondary. Primary iron ore deposits can be formed by magmatic, contact metasomatic, and hydrothermal processes.
